Snowbunny was the nickname of an ice-themed villainess who appeared in Captain America #392 in the service of lesbian supervillainess Superia to antagonize Captain America and his then-girlfriend Rachel Leighton, aka Diamondback, while Captain America was disguised in ladies' clothing following his escape from Superia's laboratory, wherein he had been subjected to synthetic estrogen injections for the purpose of turning him into a woman.
